## Description

Get On The Water

Review: Great filler from west system A++++++
Review: This stuff works great!! It’s not easy to mix into the epoxy, it’s so insanely light, it just floats away if you’re not very very careful!! Add a little at a time, mix inside a garage or somewhere the wind can’t get to the mixing bowl. Once it’s mixed in, it does a great job thickening up the epoxy. Great for vertical surfaces as it really holds upright well once mixed to the proper thickness.
